So I have gotten my phone connected and everything has worked fine,. But when I attempt to "cd" to a certain directory I would like to add a file too, it says "No such Directyory exists" and I have checked and rechecked all the names with the ones posted in the Wiki.. I have attempted accessing every directory listed, none of them are working.. What am I doing wrong??

Your jailbreak didn't work correctly. Do it again, or download a fresh version of jailbreak and try again. At any time from iphoneinterface you can type ls and hit return to test it out. If you only see 5 or so directories, it didn't work.
